Think of this as one train standing still
and the other train moving at the sum
of their speeds
Let +t+ = time in hrs for them to
pass each other
+26+=+%28+45+%2B+60+%29%2At+
+26+=+105t+
+t+=+26%2F105+
+t+=+.2476+
+.2476%2A60+=+14.86+
They will pass each other in 15 min
-----------------------
check:
+d%5B1%5D+=+45t+
+d%5B1%5D+=+45%2A.2476+
+d%5B1%5D+=+11.142+
and
+d%5B2%5D+=+60t+
+df%5B2%5D+=+60%2A.2476+
+d%5B2%5D+=+14.856+
+d%5B1%5D+%2B+d%5B2%5D+=+11.142+%2B+14.856+
+d%5B1%5D+%2B+d%5B2%5D+=+25.998+
close enough -OK
